Method and apparatus for mitigating network failures

摘要

A network may include a method that includes, for example, receiving a communication request responsive to a telephone number mapping query failure, where the communication request is initiated by an originating communication device requesting a communication session with a terminating communication device, foregoing initiating the communication session as a circuit-switched communication session responsive to determining that the originating communication device and the terminating communication device are enabled to use packet-switched communications, and instructing a second network node to initiate the communication session as a packet-switched communication session between the originating communication device and the terminating communication device responsive to the determination. Other embodiments are disclosed.

1. A method, comprising:
receiving a communication request from an originating communication device, wherein the communication request includes a first codec, a terminating party identifier of a terminating party communication device, and an originating party identifier of the originating communication device; performing a telephone number mapping query, wherein the telephone number mapping query includes the terminating party identifier of the terminating party communication device and the originating party identifier of the originating communication device; receiving a failure notice of a failure of the telephone number mapping query; providing, to a breakout gateway control function system comprising a processor, the communication request responsive to the failure notice; providing, by the breakout gateway control function system, the communication request to a multiple systems coupling server, wherein the multiple systems coupling server downgrades the first codec to a second codec for circuit switched communications; determining, by the multiple systems coupling server, that packet-switched voice over long-term evolution communications is possible according to the originating party identifier of the originating communication device and the terminating party identifier of the terminating party communication device; upgrading, by the multiple systems coupling server, the second codec back to the first codec responsive to the determination that the packet-switched voice over long-term evolution communications is possible; and instructing, by the multiple systems coupling server, a call session control function device to initiate a communication session as a packet-switched communication voice over long-term evolution session between the originating communication device and the terminating party communication device responsive the determination that the packet-switched voice over long-term evolution communications is possible.
